Heat
oil in a small pan over medium low. Add Ginger and Garlic and stir for 1
minute. Add Soy Sauce, Water and Brown Sugar and bring to a boil. Let
boil 3-5 mints or until slightly thickened. Set aside. Now add thinly
sliced Beef and toss with Cornstarch. Gently shake off any excess. Place
1 tbsp at a time of oil in a pan or wok and heat over medium high heat.
Cook the Beef in small batches for about 2 mints. It doesn't need to
cook all of the way through, it will cook completely when combined with
the Sauce. Once all the Beef has been cooked, combine with the Sauce and
heat over medium until hot and bubbly. Remove from heat and stir in
green onions. MONGOLIAN BEEF is ready to serve. Serve with boiled rice.
